Application filed' august To all fwhom z't may concern:

Be it known that l, Jargon Dzmrnmwioz, a subject of the Emperor of Austria, and a resident of Perth Amboy, in the county of Middlesex and State of New Jersey, have invented certain new and useful improve ments in Control-Valves, of whichthe following is a speciiication, A s invention relates to improvements in means for preventing the overflow of bath tubs and 'has as its principal object the provision of means whereby the rising of the water in the .tub automatically closes a valve at the terminal ofthe supply pipe, thus enabling a person to turn the wateren and temporarily leave the saine unattended.

`f lhis and other objects as simplicity, com pactness and durability', are attained by the novel construction and combination of parts hereafter described and shown in the acforming a part of this d1sclosure andv iii-'which Figure l is a vertical sectional View talren through a conventional type of bath tub indicating the application of the invention'.

Fig. 2 is an enlarged sectional view or" the control valve, and

f Fig. 3 is a similarsectional view showing control valve.

- ln the drawing the numeral 10 is applied.

. to thev bath tub resting uponlfeet l1 on its foundation and has leading to it asupply pipe i2 provided with acontrol valve 14 arranged inthe faucet, or delivering element 15, which in this case is preferably provided with a screw threaded end 16 to which the ddevice may be attached.

lnthe form shown in Fig. 2 the apparatus is seen to be composed of an upper hollow body V18 joined at its cylindrical lower end 19 by screw-threads to the lowerj element 20g theI latter being bell-shaped atits, bottom.

Formed integrally with this element 1 s a dish 22 having a central circular opening 23, provided with a valve seat 24. Rising from the disk 22 are lugs 26 1n which .1s pivoted a disk valve 27 by means of the pin 28, the same beinglso arranged that when 1n a raised position no obstruction 1s presented in the clear passage from the faucet through the apparatus Formed, exteriorly of the bell shaped Specilication of Letters Patent.

lower portion are other pivoted a lever 3l, extending through the opening 32 and carrying a frame 33 containing a hollow spherical lioat 34. The outer end of the lever 31 has pivotally engaged with it a linlr 38 `connecting at its upper end with. another lever 39, fulcrumed at 40 on the bracket arm 4l, the lever eX- tending into. the body 20, through the opening 42 and being connected at its inner end with a link 43 engaged with. lugs 44 attached to the lower side of the disk valve 2'?.

When the water rises in the tub 10- and before it reaches the height of the outlet pipe 45 it will cause thefloa't to rise, and through the system of levers close the `disk valve 27 upon the annular seat 24 efi'ectually preventing a further inlet of waterA to the tub.

Thus one is enabled to turn on the water, eitherhot or cold or combined, as may be desired, and while preparing for the bath oroccupied with other matters, -allow the tub to be iilled to a desirable height with-- out danger of overflowing or wasting the water or drawing an undue quantity therein.

In the adaption shown in Fig. 3 the valve body 48 is shown to be somewhatdilferent in shape, as is the lower element 49 secured by screw threads 50 and having'a 'plate 52 provided with a central circular opening 53 adapted to be covered by the disk 55, hingedly engaged by a pin 56 to the ,lugs 57 formed with the plate 52 and operated through the link 59, the lower end of which lugs 30 in which is is engaged with the inner end 6l of thev lever 62, pivoted at 60 to the element 49 and engaged with a frame A63 carrying the float 34 aspreviously described. The operation of the two structures shown are substantially the same and will be'readily understood by the foregoing description taken in connection with the drawing.

Having thus described my invention what l claim as new and desire to secure by Letters Patent, is

In a device of the class described the combination of a faucet and lioat controlled ./means for stopping the flow of water therethrough comprising a hollow' body member in screw threaded engagement with said faucet, and provided upon its lower interior face with screw threads, a second holow member secured by screw-threaded engagement to said body ywith an aperture Yto the top portion of a valve 'seat formed in said disk, a valve disk pivoted upon said provided with and adJacent l5 Said-second. member,

member,v a

formed integral irst mentioned disk and float controlled disk means for opening and closing said valve disk as and for the purposes set forth.
